**5,005,005,005**

- Write the following in words 80,000,045, 000 (2mks)
**Eighty billion, forty five thousand**

- Five billion, five million, five thousand and five.
- Express the following numbers as a product of their prime factors.
- 900 (2mks)
**= 2**^{2}x 3^{2}x 5^{2} - 300 (2mks)
**= 2**^{2}x 3 x 5^{2} - 196 (2mks)
**= 2 × 2 × 7 × 7**

= 2² × 7² - 64 (2mks)

**2 x 2 x 2 x 2 x 2**

= 2^{5}

- 900 (2mks)
- Use the number line to perform the following.
- (+5) – (–2) (2mks)
- (+2) + (+3) (2mks)
- –7–(–8) (2mks)

- The G.C.D of two numbers is 12 and their L.C.M is 240. If one of the numbers is 60. Find the other number. (3mks)
**N = GC.D x L.C.M 12 x 240 = 48**

60 - If x = –2, 7 = –6 and Z = 4. Find the values of
- 4xy (3mks)

z

4 x – 2 x - 6 = 48 = 12

4 4 - 4z+2y-x (3mks)
**(4 x 4) + (2x – 6) –(–2)**

16 + (–12) – (–2)

16 – 12 + 2 = 6

- 4xy (3mks)
- Three tanks are capable of holding 36, 84 and 90 Litres of milk. Determine the capacity of the greatest vessel which can be used to fill each one of them on exact number of times. (3mks)
**3 x 2 = 6litres** - Test whether the following numbers are divisible by 3. (4mks)
- 1257
**1+2+5+7=15 divisible by 3** - 7203
**7+2+0+3=12 divisible by 2**

- 1257
- Three bells ring at intervals of 40 minutes, 45 minutes and 60 minutes. If they ring simultaneous at 6.30 a.m. at what time will they next ring together. (4mks)
